Product details
Overview
PD55025TR-E from STMicroelectronics is a N-channel enhancement-mode lateral MOSFET RF power transistor in common-source configuration, rated for 25 W output power at 500 MHz with 14.5 dB gain and 50% drain efficiency under 12.5 V supply. It features 40 V drain-source breakdown voltage, 7 A continuous drain current, and 1.2 °C/W junction-to-case thermal resistance. Designed for car mobile radio amplifiers and broadband industrial RF transmitters operating up to 1 GHz.
For engineers reviewing the PD55025TR-E datasheet, PD55025TR-E pinout, PD55025TR-E application, or PD55025TR-E equivalent, this device requires attention to gate drive stability, thermal management on copper-clad RF PCBs, impedance matching networks for 175–1000 MHz operation, and PowerSO-10RF package soldering guidelines per AN1294.
Technical Context
This LDMOS transistor operates in enhancement mode with zero gate threshold bias required for conduction initiation. Its lateral structure enables high linearity and thermal stability across wideband frequencies, supported by low input/output capacitances (CISS = 86 pF, COSS = 76 pF) and minimal feedback capacitance (CRSS = 5.8 pF).
The device uses common-source topology with isolated source terminal for optimal grounding in RF PA stages. It delivers stable 25 W POUT at 500 MHz with 20:1 load mismatch tolerance, enabling robust operation in mobile radio front-ends without external VSWR protection circuitry.
Key Specifications

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4, 5, 6, 7, 8 | Source | Common return path for RF and DC; electrically tied to thermal pad - must be soldered to large copper area for heat dissipation and RF grounding |
| 9 | Gate | High-impedance control terminal; requires stable DC bias and RF decoupling to prevent oscillation and gate damage |
| 10 | Drain | RF output node; connects to output matching network and DC feed choke; carries full RF current and DC supply |
Key Features

FAQ
What is the recommended gate bias voltage range for PD55025TR-E?
The device operates with VGS(Q) between 2.0 V and 5.0 V at ID = 100 mA (static condition). For RF operation at 200 mA quiescent current, typical gate bias is 3.2–3.8 V. Exceeding 5.0 V risks gate oxide degradation; below 2.0 V causes insufficient channel enhancement and gain collapse. Bias stability must be maintained within ±50 mV using low-noise regulators and RC filtering.
Can PD55025TR-E be used at 28 V supply voltage?
No. Absolute maximum V(BR)DSS is 40 V, but the device is characterized and qualified only for 12.5 V and 13.8 V operation per datasheet Tables 5 and 13. At 28 V, gate-source voltage margin shrinks dangerously, CRSS increases nonlinearly, and thermal runaway risk rises sharply above ID = 2 A. ST does not specify safe operating area or reliability data beyond 15.5 V.
Is the PowerSO-10RF package lead-free and RoHS compliant?
Yes. PD55025TR-E uses ST's ECOPACK®-compliant PowerSO-10RF package, meeting RoHS Directive 2011/65/EU and REACH SVHC requirements. The device is rated MSL 3 per J-STD-020B and qualified for lead-free reflow profiles with peak temperature ≤260 °C. Full compliance documentation is available via ST's quality portal.
How does PD55025TR-E perform at 175 MHz compared to 500 MHz?
At 175 MHz, POUT remains 25 W with 14.5 dB gain and 50% efficiency (Figure 16), but input return loss improves to –25 dB (vs –15 dB at 500 MHz), easing matching network design. S21 phase shift is reduced, enhancing group delay flatness for narrowband FM modulation. Thermal resistance remains unchanged, permitting identical heatsinking.
